Research Projects

A cropping system based on adding organic matter through soil amendments and organic fertilizers can restore soil health and strawberry yields by limiting the occurrence of disease symptoms.

Using a split-split-plot design, this study tested three variables: soil tillage, crop rotation in organic production, and fertilization with manure or compost.

The data generated by this project was used to develop a new NPK fertilization chart that reflects technical, agronomic, and environmental issues.

This project was aimed at determining the nutrient needs of beets based on soil texture and phosphorus and potassium levels under Québec growing conditions.

The aim of this project was to gather data on the nutritional requirements of barley to better equip producers, extension agents, and other industry stakeholders.

The aim of this project was to gather data on the nutritional requirements of oats to better equip producers, extension agents, and other industry stakeholders.

To provide information on the fertilizing value and environmental impact of spreading pig manure at different times, the project compared the effect of mineral fertilizer in early fall, late fall, and in the spring.

The purpose of the project was to assess the benefits of controlled farm drainage under current and future climatic conditions to meet the water needs of field crops and rural communities while reducing nitrogen and phosphorus flows into watercourses.

IRDA was in charge of conducting the economic analysis for this project carried out by Club agroenvironnemental de l’Estrie (CAE Estrie).

This project aimed to evaluate the purification capacity of different configurations of swales planted with shrubs or perennial grasses to serve as vegetative filter strips.

The aim of this project was to consolidate current scientific knowledge with a view to developing a spatially referenced tool to predict diffuse sediment, nitrogen, and phosphorus exports at the farm and watershed scale.

The project evaluated and compared the effectiveness of two types of subsoil plows (mounted on a bulldozer or a tractor) operated parallel and perpendicular to the tile drains to improve soil drainage conditions and productivity compared to control plots.

To increase the productivity of potato production systems and preserve soil quality, we need to enhance our knowledge of interactions among biological, physical, chemical, and agronomic characteristics of cultivated soils in various environments.
